Diagnostic Procedure with Diagnostic Trouble Code (DTC)
ENGINE (DIAGNOSTICS)
Step Check Yes No
1CHECK HARNESS BETWEEN ECM AND OIL
FLOW CONTROL SOLENOID VALVE.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from ECM and
oil flow control solenoid valve.
3) Measure the resistance between oil flow
control solenoid valve and engine ground.
Connector & terminal
(E67) No. 1 — Engine ground:
(E67) No. 2 — Engine ground:
Is the resistance more than 1
MΩ?
Go to step 2.Repair the short
circuit between
ECM and oil flow
control solenoid
valve connector.
2CHECK OIL FLOW CONTROL SOLENOID
VALVE.
1) Remove the oil flow control solenoid valve
connector.
2) Measure the resistance between oil flow
control solenoid valve terminals.
Te r m i n a l s
No. 1 — No. 2:
Is the resistance between 6 —
12 Ω?
Repair the poor
contact of ECM
and oil flow con-
trol solenoid valve.
Replace the oil
flow control sole-
noid valve. to ME(H6DO)-77,
Oil Flow Control
Solenoid Valve.>

1CHECK HARNESS BETWEEN ECM AND OIL
FLOW CONTROL SOLENOID VALVE.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from ECM and
oil flow control solenoid valve.
3) Measure the resistance between ECM and
oil flow control solenoid valve.
Connector & terminal
(B137) No. 15 — (E68) No. 1:
(B137) No. 14 — (E68) No. 2:
Is the resistance less than 1
Ω?
Go to step 2.Repair the open
circuit of harness
between ECM and
oil flow control
solenoid valve
connector.
NOTE:In this case, repair
the following item:
•Open circuit
of harness be-
tween ECM and
oil flow control
solenoid valve
connector
•Poor contact
of coupling con-
nector
2CHECK OIL FLOW CONTROL SOLENOID
VALVE.
1) Remove the oil flow control solenoid valve
connector.
2) Measure the resistance between oil flow
control solenoid valve terminals.
